upper side line) and door latch heads pass through the latch holes
correctly.
5. Fasten upper and lower hinges firmly to oven cavity with two (2)
screws on each hinge.
NOTE: After any service to the door;
1) Make sure that door sensing switch, secondary interlock
switches (1), (2) and monitor switches (1), (2) are operating
properly. (Refer to chapter “Test Procedures”.).
2) An approved microwave survey meter should be used to
assure compliance with proper microwave radiation emis-
sion limitation standards.
3. DOOR ADJUSTMENT
Door adjustment is performed with the door properly installed and
closed and while the oven hinges are loose.

parallel to the bottom of the control panel assembly.
3. Tighten the upper and lower oven hinge screws.
3.1. After adjustment, make sure of the following:
1. Door latch heads smoothly catch the latch hook through the latch
holes, and the latch head goes through the center of the latch hole.
2. Deviation of the door alignment from horizontal line of cavity face
plate is to be less than 1.0mm.
3. The door is positioned with its face depressed toward the cavity
face plate.
4. Re-install outer case and check for microwave leakage around
door with an approved microwave survey meter. (Refer to Micro-
wave Measurement Procedure.)
NOTE: The door on a microwave oven is designed to act as an elec-
tronic seal preventing the leakage of microwave energy from
oven cavity during cook cycle. 
This function does not require that door be air-tight, moisture
(condensation)-tight or light-tight. Therefore, occasional
appearance of moisture, light or sensing of gentle warm air
movement around oven door is not abnormal and do not of
themselves, indicate a leakage of microwave energy from
oven cavity. If such were the case, your oven could not be
equipped with a vent, the very purpose of which is to exhaust
the vapor-laden air from the oven cavity.
